SYNOPSIS. A survey of 22 Western Painted Turtles (WPT), Chrysemys picta belli Gray; 2 Map Turtles (MT), Graptemys geographica Le Sueur; 8 False Map Turtles (FMT), Graptemys pseudogeographica Gray; 26 Illinois Mud Turtles (IMT), Kinosternon flavescens spooneri Smith; and 5 Spiny Softshell Turtles (SST), Trionyx spiniferus Le Sueur, revealed the presence of 10 species of coccidia. The species found, the shape and average length‐width dimensions (in micrometers) of their oocysts, and the respective hosts from which they were isolated were as follows: Eimeria chrysemydis Deeds & Jahn, slightly pear‐shaped (27.6 × 17.0), from 5 WPTs; Eimeria delagei marginata Deeds & Jahn, markedly pearshaped (22.1 × 17.6), from 2 WPTs, 1 MT, and 3 FMTs; Eimeria graptemydos sp. n., broadly ellipsoid to subspherical (12.6 × 11.4), from 10 WPTs, 2 MTs, and 5 FMTs; Eimeria lutotestudinis sp. n., broadly ellipsoid to subspherical (11.9 × 10.8), from 4 IMTs; Eimeria mascoutini sp. n., broadly ellipsoid to subspherical with outer surface of oocyst wall mammillated (14.0 × 11.9), from 2 SSTs; Eimeria mitraria (Laveran & Mesnil), asymmetrically ellipsoid, bearing 1 or 2 conical projections at the polar end and 2 or 3 at the antipolar end (10.0 × 7.6), from 7 WPTs, 1 MT, 3 FMTs, and 4 IMTs; Eimeria pseudogeographica sp. n., narrowly ellipsoid to slightly ovoid (19.5 × 13.5), from 5 WPTs and 3 FMTs; Eimeria tetradacrutata sp. n., spherical to subspherical with outer surface of oocyst wall mammillated (19.5 × 19.2), from 1 WPT; an Eimeria sp. narrowly ellipsoid, bearing 2 conical projections at the polar end and 2 at the antipolar end (23.8 × 13.2), from 1 MT; and Mantonella hammondi sp. n., conical to narrowly ellipsoid, bearing 1 conical projection at the polar end and 2 or 3 at the antipolar end (14.3 × 7.1), from 1 IMT. The overall infection rate for the 63 turtles examined was 54.0%.
